Mechanical dynamics are affected by gravity.


Out-of-level conditions on machinery could result in excessive thrust loads on rotating equipment. Fluids, used for lubrication and in the manufacturing process, may be dependent upon a level environment. Materials traveling through continuous web systems may also be affected by out-of-level conditions.

To establish a level condition is said to be “horizontal or parallel to earth”. The optical alignment industry utilizes a “precision optical level” to measure level conditions and discrepancies. The precision level relies on an extremely accurate level vial attached parallel to a telescope. Using established horizontal optical planes, and in conjunction with optical scales, components can be optically measured for their level condition from end to end.
